Book excerpt: Vector orthogonal frequency division multiplexing (V-OFDM) for single transmit antenna systems is a general block based transmission scheme, where OFDM and single carrier frequency domain equalizer (SC-FDE) are two special and extremal cases. ☐ In this thesis, algorithms of detecting and Turbo decoding for V-OFDM systems are simulated and discussed. We use quadrature amplitude modulation (QAM) to modulate Turbo coded V-OFDM (TC-V-OFDM) system, the output of detecting part is soft information, therefore the Turbo decoding algorithm need to be modified. By modifying the maximum a posteriori (MAP) algorithm, a single input single output (SISO) MAP Turbo decoding algorithm has been discussed in this thesis. ☐ Then, the theory of decoding turbo code is applied to the detection of signals by the joint of equalization and decoding. The recursive equalization algorithm of MAP and linear MMSE are discussed in detail. The lower-complexity MMSE equalization algorithm has eventually been chosen as the simulation algorithm because that the complexity of MAP will increase exponentially with the modulation order and the memory length of ISI channel. The characteristics of V-OFDM’s cyclic prefix reduce the complexity of MMSE equalizer further. ☐ Turbo Receiver of TC-V-OFDM system is realized in this thesis by applying the recursion, and this not only increases the diversity gains, but also decreases bit error rate (BER) of the system, therefore the performance of the system is improved greatly. ☐ Key Words: Turbo code; Turbo Receiver; V-OFDM; MMSE

Download or read book Multi Carrier Spread Spectrum written by Khaled Fazel and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The benefits and success of multi-carrier (MC) modulation on one side and the flexibility offered by the spread spectrum (SS) technique on the other side have motivated many researchers to investigate the combination of both techniques since 1993. This combination known as multi-carrier spread spectrum (MC-SS) benefits from the advantages of both systems and offers high flexibility, high spectral efficiency, simple detection strategies, narrow-band interference rejection capability, etc. The basic principle of this combination is straightforward: The spreading is performed as direct sequence spread spectrum (DS-SS) but instead of transmitting the chips over a single carrier, several sub-carriers are employed. The MC modulation and demodulation can easily be realized in the digital domain by performing IFFT and FFT operations. The separation of the users' signals can be performed in the code domain. MC-SS systems can perform the spreading in frequency direction, which allows for simple signal detection strategies. Since 1993, MC-SS has been deeply studied and new alternative solutions have been proposed. Meanwhile, deep system analysis and comparison with DS-CDMA have been performed that show the superiority of MC-CDMA.

Download or read book OFDM and MC CDMA written by Lajos Hanzo and published by John Wiley & Sons. This book was released on 2007-01-11 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communications has witnessed a tremendous growth during the past decade and further spectacular enabling technology advances are expected in an effort to render ubiquitous wireless connectivity a reality. Currently, a technical in-depth book on this subject is unavailable, which has a similar detailed exposure of OFDM, MIMO-OFDM and MC-CDMA. A further attraction of the joint treatment of these topics is that it allows the reader to view their design trade-offs in a comparative context. Divided into three main parts: Part I provides a detailed exposure of OFDM designed for employment in various applications Part II is another design alternative applicable in the context of OFDM systems where the channel quality fluctuations observed are averaged out with the aid of frequency-domain spreading codes, which leads to the concept of MC-CDMA Part III discusses how to employ multiple antennas at the base station for the sake of supporting multiple users in the uplink By providing an all-encompassing self-contained treatment this volume will appeal to a wide readership, as it is both an easy-reading textbook and a high-level research monograph.

Download or read book The Vienna LTE Advanced Simulators written by Markus Rupp and published by Springer. This book was released on 2016-03-23 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the Vienna Simulator Suite for 3rd-Generation Partnership Project (3GPP)-compatible Long Term Evolution-Advanced (LTE-A) simulators and presents applications to demonstrate their uses for describing, designing, and optimizing wireless cellular LTE-A networks. Part One addresses LTE and LTE-A link level techniques. As there has been high demand for the downlink (DL) simulator, it constitutes the central focus of the majority of the chapters. This part of the book reports on relevant highlights, including single-user (SU), multi-user (MU) and single-input-single-output (SISO) as well as multiple-input-multiple-output (MIMO) transmissions. Furthermore, it summarizes the optimal pilot pattern for high-speed communications as well as different synchronization issues. One chapter is devoted to experiments that show how the link level simulator can provide input to a testbed. This section also uses measurements to present and validate fundamental results on orthogonal frequency division multiplexing (OFDM) transmissions that are not limited to LTE-A. One chapter exclusively deals with the newest tool, the uplink (UL) link level simulator, and presents cutting-edge results. In turn, Part Two focuses on system-level simulations. From early on, system-level simulations have been in high demand, as people are naturally seeking answers when scenarios with numerous base stations and hundreds of users are investigated. This part not only explains how mathematical abstraction can be employed to speed up simulations by several hundred times without sacrificing precision, but also illustrates new theories on how to abstract large urban heterogeneous networks with indoor small cells. It also reports on advanced applications such as train and car transmissions to demonstrate the tools’ capabilities.
